To all whom. it may coin-cern:

Beit known that I, Louis YiLrtrrn, a subject ot' the Kingdom ot Greatlritain. residing in Joliet, in the countv ot lill and 'State otIllinois. have invented a new andy double doors for coke-ovens, and theinvention consists in `the novel parts, and conibinations ot parts anddevices, hereinafter particularly described, set forth, shown, andclaimed.

In the accompanying drawings which form a part of this specification,Figure 1 is a front View of a coke-oven showing a face view of the outerdoor, applied and sealed; Fig. 2 is a sectional view on the line 5).-2of Fig. 1, a portion being added to the' section. above `the limits ofsaid F 1: Fig. 3 1s a cross section on the line 3-3 ot i Fig. 1, thesection being, however, upon a larger scale than said Fig. l: Fig.A 41sa tace view of the outer door with the cotter bars removed therefrom;Fig. 5 is a fragmentary view of the face of the inner door showing itstwo pivoted latches.

Tn said drawing ll is the interior ot the oven; 12 the flooring thereof,13 the. inout-h or door opening of said oven, made with an open-ingsomewhat Haring to more readil7 receive and center the plug door. Thisplug-door, or inner door, consists of the rectangular frame, 14, having'the inwardlv projecting flange, 15, extending entirelyY around the door,td receive and retain the tire-brick lining 1G, and having the laterallyprojecting flange 17 to set against the face 1S of the door masonry jambat the top and sides ot the door. At, the bottom ot the plug-door itsmetal trame is made with an opening through to receive the single plugbrick 19. rl`his openingis'intended for the introduction of an oil orgas burnerin the preliminariv heating ot the oven, the burner beingthrust. through and Aburned unt-il the oven is preliminarily warmed,after which the burner is withdrawn and the plug brick inserted closingthe opening previous to the filling of the oven with coal for coking.20, 20 show the usual buck-stays of the oven.

,above the side hooks.'

Serial No. 613,358.

91, 2l are two brackets one at each side et and below, the door opening.These brackets are secured to the buck-stays; Surrounding` the dooropening is a metal jamb 22, secured to the brackets Q1. The innerlateral tace ot this jamb grooved as at 23. Vlpon the tace ot the plugdoor are secured lifting sockets Q4, 24, to receive the lifting hooksof, preferably, a suitable twin crane to be used for opening and closingthe doors b v a lifting and witlulrawing act ion, Pivoted to the tace of'the plug door at each ot the said sockets Q-l are the latches to engagethe groove 253 in the jamb to hold thel plug door in place. The loweredge of these latches 2li extend -iar enough below the downwardlyopening mouth of the sockets 24 so that when the liftingl hooks engagesaid sockets the. latches, by this act, will he lifted, or turned -upon`their pivots, and un.- latched 'from the groove Q3. One ot the lat-chesengages the jaml'i at one side, and the other at the other side. of thedoor, as will be understood 'trom Fig. 5.

re now go to a description of the outer door. This outer door, QG, is ametallic one, made with an inwardly projecting sharp 'flange Q7, allaround atthe sides and top and bottom, adapted to encounter an asbestosor other packingl cushion 2S placed preferably in a groove, 29, in theouter face ot the door janib 0n the outer face of this-door are thelifting sockets, 30, similar to the sockets upon the outer tace of theplug door, and for the same purpose, namel)vv to receive the liftinghooks for the removal of the door. Cotter-bins, 2,1, are looeelj)7attached to the door b v pins 32, so as to have a movement to someextent toward and away from the door. The ends of these Cotter barsextend at eaeh side beyond the sides of the door` 'and .tar enough toengage the upwardly pointing hooks, 33, secured to each side of the doorjanib 22. At the center ot each Cotter-bar is a screw, 34, which mayVhave a square head, to receive a removable operating crank, 36. Thisscrew is tapped into the cotter bar and opposite to it in the face ofthe door is the shallow cavity 37 to receive the point of the screw.

W'hen the outerdoor is to be set in place, it is rst placed, by thelifting hooks, into approximate position, the Cotter barsbeing The dooris vthen lowered until the projections, 40, at the i erally, from oneside orthe other, until .it

is exactly centered. The door, as will be seen, is thus centered at thetop and bottom and sides .so that its inwardly projecting sharp flangeis brought against the asbestos packing always in exactly the sameplace. This insures a perfect seal, no matter whether the metallicparts-may have warped or not; because the impression having been made inthe packing remains the saine and the door is always'brought to and sofits it. When the door is in proper position the screws are turnedforcing the ends of the Cotter-bars out against the retaining hooks andthe edges of the flange of the door against the joint. i I claim l. Thecoke-oven closure comprising in combination an unattached inner plug.door and an unattached outer door, means for sealing said outer doorl.and both applicable packing thus forminga perfect and removable by abodily lateral movement and entirely detachable from the oven,substantially as specified.

2. The coke-oven closure comprisingin combination, an unattached innerplug door and an unattached -outer sealing door, both 'applicable andremovable by a bodily lateral movement and entirely detachable` from theoven, the inner' plug'door being furnished with lire-brick insulationand the outer door being provided with a continuous sealing flangeadapted to set against-a packngi on the door` j amb, substantially asspeci- 3.
